I wanted to personally thank Nathan for all his help in diagnosing the gremlin I've been fighting after the install of my aux in bypass. He was quick to the response and gave me insight into what might be the problem. Advice... Make sure you make the connection from the heat sink (back plate) TIGHT where is sits up agains the little black magnet looking thing (MOSFET). Otherwise your CD player will overheat and go nuts on you.
